What Happens When You Establish SAM Seeing Garment Image

I am following one Facebook group, where industrial engineers and planning engineers post questions and share knowledge. Indeed, it is a good group for many for leaning and getting clarification on new topics and industry terms. In that group, I saw one discussion where one IE posted one garment image and asked – what would be the SAM of the sample garment?

My objective of posting this article, just to tell you that it is not a good idea to guess garment SAM. You will not get the correct SAM if you try to establish it seeing a garment sample. Instead, it will mislead you.

I am sharing the garment image here.

SAM for a Garment
Image is taken from the Facebook group discussion

In case you have already made the same garment and know the garment details, you probably give correct SAM by seeing an image (front, back and components). 

SAM of the garment 

In the discussion, more than 25 members shared their estimated SAM. They tried to guess possible SMV of the garment shown in the above image. Here is a list of responses. You can see the SAM range from 6.25 minutes to 24 minutes. Which one will you pick for your factory?
  1.  9 minutes
  2. 12 minutes
  3. 22 minutes
  4. 20 minutes
  5. 10 minutes
  6. 19 minutes
  7. 12 minutes
  8. 18.235 minutes
  9. 13.5 minutes
  10. 17 minutes
  11. 24 minutes
  12. 9-10 minutes
  13. 14 minutes
  14. 13 minutes
  15. 10-13 minutes
  16. 14 minutes
  17. 13.5 – 14 minutes
  18. 6.25 – 7.65 minutes
  19. 13 minutes
  20. 10 minutes
  21. 7-8 minutes
  22. 7-8 minutes.
  23. 11-13 minutes
  24. 9 minutes
  25. 20 -23 minutes 
I don’t know which one is correct. 

Many of the respondents mentioned that it is difficult to estimate the product SAM (SMV) by seeing the image only. Some of the engineers asked further questions – so that they can give accurate information. Like, "I need to check every process (operations) of the garment. There might be top-stitch but not visible in the image".

You can give estimated SAM data, but you need to know all process, need to see all seams clearly, stitch type and machine that could be used for seams. Length of the seam need be considered for estimating SAM. SAM depends on many other parameters like workstation layout, allowances added.
